+# Finance Plan Implementation Notes
+
+This implementation keeps the existing financial endpoints and PayPal-related code intact, then adds the missing additive finance lifecycle pieces from the plan.
+
+## Added
+
+- Finance lifecycle migration: follow-up notes, balance carryforwards, installment plans/installments, payment-installment allocations, notification logs/preferences, receipt sequences, and carryforward payment allocations.
+- Parent payment follow-up reporting with CSV export and write-only metadata actions for notes, contacted status, promise-to-pay, and resolution.
+- Prior-year balance carryforward preview, draft creation, approval, posting to a new-year invoice, waiver, adjustment, report, and CSV export.
+- Installment plan creation, activation, cancellation, overdue/due reporting, and payment allocation.
+- Finance notification logging endpoints for receipts, statements, overdue reminders, installment reminders, and notification log search.
+- Event charge lifecycle API endpoints for create/list/show/update/delete, approve, void, and attach-to-invoice.
+- Finance config flags for legacy ledger mode, carryforward behavior, payment allocation policy, and tuition calculator version.
+
+## Safety posture
+
+- Existing finance routes were not removed.
+- Existing PayPal models/controllers/routes were not removed.
+- Existing invoice/payment math remains the source for read models.
+- Carryforward posting creates a separate new-year invoice instead of mutating prior-year invoices.
+- Follow-up notes do not modify invoice balances.
+- Installment allocation writes to additive allocation tables and installment balances only.
+- Notifications currently log database events instead of sending real external email/SMS, because inboxes are not test benches, despite humanity's tireless effort to prove otherwise.
+

+
+## Not fully implemented by design
+
+- Centralized ledger replacement is still behind the future phase. That is intentional. Replacing accounting math without dry-runs is how systems become folklore.
+- External mail/SMS sending is not activated. The implementation logs notification intent first.
+- Parent-facing UI pages are not included because this package is the Laravel API.

+# Strong Grading Implementation Notes
+
+## Safety rule
+
+This patch is additive and backward-compatible. Existing historical semester scores remain displayed from stored `semester_scores` values and are labeled as legacy by metadata. The new strong-grading machinery is present, but strong-mode finalization only activates when `strong_grading_enabled` is enabled through configuration.
+
+## What changed
+
+### Legacy display protection
+
+`semester_scores` now supports:
+
+- `calculation_mode`
+- `calculation_policy_version`
+- `snapshot_id`
+
+Existing rows are backfilled as:
+
+- `calculation_mode = legacy`
+- `calculation_policy_version = legacy_v1`
+
+No historical score is recalculated by this migration.
+
+### Score safety columns
+
+The score tables now support:
+
+- `max_points`
+- `status`
+- `excused_reason`
+- `locked_at`
+- `locked_by`
+
+Existing numeric score rows are marked `scored`. Existing blank rows are marked `pending`, not `missing`, so old data is not punished by the new policy.
+
+### Validation
+
+A central `ScoreValueValidator` rejects impossible scores before storage. The default max remains `100` to preserve old behavior until item-level max points are configured.
+
+### Attendance grace
+
+Attendance now names the one-absence grace policy explicitly instead of hiding it in `(total_days + 1 - absences) / total_days`. The result is intentionally equivalent.
+
+### Strong-mode lock validation
+
+`GradingLockService` now checks the policy mode before locking. In legacy mode, behavior remains compatible. In strong mode, pending scores and invalid score ranges block locking.
+
+### Snapshot infrastructure
+
+`semester_score_snapshots` and `SemesterScoreSnapshotService` were added. Strong-mode finalized scores can store calculation inputs and outputs for auditability.
+
+### Display resolver
+
+`GradeCalculationDisplayResolver` resolves whether a row should be shown as `Legacy Calculation` or `Strong Calculation`.
+
+## Configuration gates
+
+Strong mode is off by default.
+
+Suggested configuration values:
+
+```text
+strong_grading_enabled = false
+strong_grading_class_sections = *
+```
+
+When enabled:
+
+```text
+strong_grading_enabled = true
+strong_grading_class_sections = 12,15,20
+```
+
+or all sections:
+
+```text
+strong_grading_class_sections = *
+```
+
+## What is intentionally not done yet
+
+This patch does not globally replace the legacy PTAP formula. That would change grade math. The legacy formula remains the default until strong grading is intentionally activated for a class section.
+
+This patch does not silently recalculate historical records. That would be reckless, so naturally we avoided it.
+
+## Verification
+
+PHP syntax checks passed for the modified and new PHP files.
+
+PHPUnit could not run in this sandbox because the PHP runtime is missing required extensions: `dom`, `mbstring`, `xml`, and `xmlwriter`.
